To ali whcm may come-m2; I with. ateii spring ends 12 anti 13 Be itlumen ti: t l, FBAIZCKS {You :clapte to make iirrn contact with the con-BRODIE, a subgect of the King of Great act'tlewiccs. members 10 and 11are Britain, and resh t of Moose Jaw, inthe Province DI bias natchewan,in the Dominion of Lanarla, have inventeii certain Controllers fo; lligas, of which the a-Lion.

This invention rela to improvements in circuit controllers for electricsigns, and the objects of the invention are to provide means bywhich amaximum amount of variation in the connection to the circuit may beobtained, and further to enable the changes to he marle with real.rapidity \vhereb an aggregation of illuminating or other devices may becaused to display different figures or ietl rsat the will of theoperator, and it consrsls excntially of the improved constructionhereinafter described. in detail in the accompanying specifications anddrawings.

In the drawings, Figure l is an elevation, partially diagrammatic, of anembodiment of the invention. Fig. 2 is a cross section through thecontrolling cylinder. Fig. fi is a perspective view of one of thecontact. devices. Fig. 4 a sectional detail through one of the contactdevices taken on the line 2-2, Fig. 3.

In the drawings like characlere of reference indicate correspondingparts in all the figures.

Referring to a rotary controlling material, supported the drawings, Arepresents cylinder of insulating in any suitable way and adapted to bedriven by suitahleineans which do not form part of the presentinvention. This cylinder carries on its surface longitudinal andperipheral rows of contact devices B which are adapted to co operatewith pairs of contact fingers C carried on a fixed support D.

The pairsof contact fingers are arranged .in a row on the fixed supportand are placed paced adietance from each other and out f electricContact with each other, being lves included in an electric circuit 14 II a source of oil; incluolm an illuminating device or lamp 15 while imay form part of a sign l each of contacts thus controlling a aimilarlamp or illuminating device.

Each of the contact devices B comprises a aoclaetmernher 1.7 formed witha base plate 18 and side plates 19 and 550 of spring metal, which fitclosely to an outwardly rnovahle part 2-1 which is pivoted or hinged tothe socket by means of a pin 22, being adapted to he ined in eitherextended or closed position hv suitable means, such as projections andformed on the side plates a :teri to fit into ccrres -ndlng depressionsK'FJCQSASQS formed. on. the. plate or lilatie- "l. A

It "will amen that the plate or blade 21 may he turned outwardly atright angles to the suriace ct the cylinder or substantially tangentialthereto and will be retained in either osition.

Till he that by selecting the various lamps to he lighted and raising orlowering the corresponding blades on the contact devices the variousletters, characters or pictures may be shown on the sign at the will ofthe operator as the cylinder revolves.

What I claim as my invention is:

1, A controller for electric circuits comprising in combination aplurality of pairs of fixed contact fingers, a. rotary cylinder ofinsulating material, a plurality of con tact devices thereon, eachhaving an ou twartlly movable part ariapted when extendeel to form aconnection between the contact fin ers of a determined pair when thecylin er'is rotated. A

A controller for electric circuits comprising in combination a pluralityof pairs of fixed contact fingers, a rotary cylinder of insulatingmaterial, a plurality of con tact devices thereon arranged in transverseanti peripheral rows, each having an outwardly movable part adapted whenextendeti to a connection between the contact. ilugera of a determinedpair when tie:- e ler i9 XQ'iuil'a.

contrr ler for electric circuits coma combination a plurality of pairsowe]: 1.5, said of fixed contact fingers, a rotary cylinder ofinsulating materlal, a p'urality of contact devices thereon, each havingan out, wardly movable pivoted blade adapted when extended to form aconnection between the contact fingers of a determined pair when thecylinder is rotated.

4. A controller for electric circuits comprising in combination aplurality of pairs of fixed contact fingers, a separate electric circuitfor each pair of fingers including an illuminating device and a sourceof power, a plurality of contact devices, each comprising a socket, ablade pivoted in the socket, said socket having pro'ections, and 15 saidblade having oorrespon ing recesses whereby the blade is held m raisedor lowercd position, said blade beingiadapted, when the cylinder isrotated, to complete the electric circuit between the contact 20 fin ersof a given pair.

n witness whereof I have hereunto set my hand in the presence of twowitnesses.
